How to wear with a swim cap

Put your swim cap on and then pull the swim cap off your ears. Put the headphones on and then pull the cap back over the ears. The cap will partially cover the ears. 

Try the included solid earplugs to get the best sound experience under water. 


How to wear with swim goggles (no swim cap)

The headphones should stay on fine without any additional help, but if you need more force to keep the headphones put - pull the swim goggle strap OVER the headphone ear hook as shown in the picture below. This will keep them firmly on and provide extra support for bone conduction. 

Try the earplugs to get the best sound experience under water.
